CLOSURE FOR, CONTAINERS.

Application filed September 5,1925, Serial No. 54,724, and in Germany Gctober 13, 1924.

My invention relates to a closure for containers and has particular reference to a closure for bottles from which the contents are to be discharged in predetermined quan tities, as for example in drops as is done in administering an anesthetic, or at a desired rate of speed as is required when us ing chemicals for fire extinguishing pur poses.

The object of the invention is to provide simply constructed means by which the closure proper may either be held firmly against the discharge opening to hermetically seal the container, or may he held the desired distance from the opening so as to permit the contents of the container to discharge therefrom in predetermined quantities and at the requisite speed.

Stated in general terms, my invention consists in providing a double armed lever which carries the closure proper, with means srch as an adjusting screw, for either holding the closure against the discharge opening of the container or an adjusted distance away therefrom, as desired and as the exigencies of the use to which the device is put may require.

Two forms of the invention are shown in the accompanying drawing, in which Fig. 1 is a side elevational view of a bottle having one form of the invention applied there to; Fig. 2 is a front elevational View of a different form of bottle provided with a slightly modified form of the invention, and Fig. 3 is a top plan view of the form shown in Fig. 2.

Referring to Fig. 1, A denotes an anesthetic bottle or container provided with an ordinary discharge nipple Zthreaded atm to receive the cap a. The bottle is also pro vided with a second discharge nipple Z containing a capillary discharge opening. Embracing the nipple Z is a collar Z), preferably a spring collar, securely held in place by the screw a. Diametrically opposite the screw a the collar 6 is provided with a pivot pin 0 constituting the fulcrum for a double aimed lever, one arm of which is denoted h and the other h. The arm it carries the closure or stopper cl for the capillary opening in the discharge nipple Z while the arm it, which is preferably knurled, con stitutes a thumb piece by means of which the lever as a whole may be manipulated. A bail spring 6 having its ends rotatable in a sleeve 0 secured to the upper face of againstthe capillary opening or a desired distance away therefrom comprises an ad-. .jdEltlIlg screw 3 threaded into the double aimed lever in the rear of its fulcrum 0 in proximity to the place where the arm it joins the arm h, it being apparent that these arms are arranged at an angle to one another. The screw is capable of being rot -rted in the lever and the lower or unheaded 32nd of the screw may take against the col- The operation of the form of inventiontion shown in Fig. 1 is substantially as follows z-To discharge the liquid through the capillary opening in the nipple Z the screw 8 is first turned in one direction (ordinarily to the left) until the unheaded end of the screw is clear of the collar Z) to permit of the lever hh being moved about its pivot c; thereafter downward pressure is applied to the arm JL until the closure cl is raised from the capillary opening the required extent to permit of discharge of contents in desired quantities and then to hold the closure (Z in the adjusted open position the screw 3 is turned in the opposite direction from that in which it was first turned until the unheaded end of the screw engages the collar 7). By this arrangement the person administering an anesthetic in drops is relieved of the fatigue and strain of keeping his thumb on the arm it, and moreover absolute uniformity of discharge is assured, which is not the case when an operator is required to hold the lever arm it. If the closure (Z is to be held against the capillary opening, either during shipment of the container or when the latter stands and has liq uid contents, the closure (Z is permitted to press against the capillary opening, as it is constrained to do by the spring 0, and the screw 3 is screwed home thereby, in effect, locking the closure in position. It will be understood that when free discharge of the contents of the bottle is desired the cap a is unscrewed and the liquid is permitted to flow out through the nipple Z.

In the form of invention illustrated in Figs. 2 and 8, the bottle B is 01 the upright type with a capillary discharge opening in its neck and the discharge nipple Z provided with the threaded end me to receive the cap a at the mouth end of the bottle.

Embracing the bottle neck is a split collar b having curved ends engaged by a spring clip f to hold the collar in place. The collar is provided with a pivot 0 serving as a fulcrum tor a curved double armed lever la b the latter arm oi the lever constituting a thumb piece against which pressure may be exerted to manipulate the lever as a whole.

At its end remote from the pivot 0 the lever arm fi is provided with a closure cl for the capillary opening in the bottle neck. Threaded through the arm b of the lever adjacent the pivotal point is an adjusting screw 5 the unheaded end oi which may take against the collar b A spring .2 coiled about the pivot 0 and having an end pres:-

ing against the inner face ot the arm in tends to force the closure (Z into seating position over the capillary opening.

The operation of this form of the invention is substantially similar to that of Fig. 1.

It the bottle contents are to be discharged through the capillary opening (Z, the screw 9 is rotated until its unheaded end is entirely out of contact with the collar If thus permitting the lever ]L /L to be moved. Thereupon pressure is exerted against the arm 71 until the arm h is unseated from the capillary opening (Z to the extent required for discharging the bottle contents through (Z in the desired quantities and at the de sired speedl Then the screw e is rotated in a direction opposite that in which it was first rotated, until the unheaded end of the screw engages the face of collar Z)". l/Vith the parts in this position the lever arms if-ZL will be held immovable by the screw 8 and discharge of the bottle contents takes place. When no further discharge is desired, the screw 5" is again rotated in the first direction 01" rotation and the spring a" will push against arm b thereby forcing arm if to seat over the opening cl I claim:

1. A closure for containers, comprising a spring pressed double armed lever, a stopper carried by one of the lever arms, and means for holding the lever in adjusted position in relation to a discharge opening in the container.

2. A closure for containers having a capillary opening, comprising a collar embracing a part of the container, a double armed lever pivoted to said collar, a stopper carried by one of the lever arms, means tending to normally seat the stopper over the opening, and means for holding the lever and stopper in adjusted position in relation to the opening.

3. A closure for containers having a capillary opening, comprising a collar embracing a part of the container, a pivot in said collar, a double armed lever fulcrumed on said pivot, one of said arms constituting a thumb piece for manipulating the lever and a stopper for the capillary opening carried by the other arm, means tending to nor mally "force the stopper into seating position over said opening, and an adjusting screw threaded through one of said arms and adapted to press against said collar to hold the lever and stopper carried thereby in ad juste d position in relation to the capillary opening.

In testimony whereof I atiix my signature.
